. if y=100 at t=4 and y=10 at t=8, when does y=1?
Answers
Answer:
I think this is the answer
Step-by-step explanation:
To solve for when y=1, we can use the slope-intercept form of a linear equation, which is y = mx + b. First, we need to find the slope (m) using the two given points:
m = (10 - 100) / (8 - 4)
m = -90 / 4
m = -22.5
Now we can use the point-slope form of a linear equation, which is y - y1 = m(x - x1), where (x1, y1) is one of the given points. Let's use (4, 100):
y - 100 = -22.5(x - 4)
Simplifying this equation, we get:
y = -22.5x + 202.5
To find when y=1, we can substitute that into the equation and solve for x:
1 = -22.5x + 202.5
-22.5x = -201.5
x = 8.96
Therefore, y=1 at approximately t=8.96.

Answer:
1: 65 in^2
2. 55 ft^2
Step-by-step explanation:
1. First you have to find the area of the trapezoid using the formula (a+b)h/2 where a= 10, b=15, and h=8. The answer will be 100. Then subtract the area of the square inside, which is 35. The final answer is 65.
2. Subtract from the dimensions of the landscape to find the dimensions of the patio. The length of the patio is 11 ft and the width is 5 ft. Therefore, the area is 55 ft^2
Answer:
Alright, helping you because I feel bad. 1) 76 in. 2) 24 in.
Step-by-step explanation:
1. [tex]A= \frac{a+b}{2} h[/tex] a= base b= base h= height Plug in the numbers, [tex](\frac{10+15}{2} ) 8= 100[/tex], but we still need to subtract the area of the un-shaded region (5×2)+(7×2)= 24
100-24= 76
2. Find the area of both landscaping rectangles, including the patio bit.
(14×2)+(8×2)=
28+16=
44in. The two rectangles are the same size, so they both have an equal area. Now we find the area of just the patio spot, W= (8-3)×2 L= (14-3)×2 W= 10 L= 22 A=32 in.
Now, we multiply by two, since we counted it twice, 64 in.
Finally, subtract 64 from the the sum of the two areas from the landscape rectangles, 88-64= 24 in.
w is directly proportional to u if w=5 when u=3,find u when w is =2/7
Answers
Answer:
u = 6/35
Step-by-step explanation:
w = k * u
w = ku
Where
k = constant of proportionality
if w=5 when u= 3
w = ku
5 = k * 3
5 = 3k
k = 5/3
find u when w is =2/7
w = ku
2/7 = 5/3 * U
2/7 = 5/3u
u = 2/7 ÷ 5/3
= 2/7 × 3/5
= (2*3)/(7*5)
= 6/35
u = 6/35

Find the area of a vertical cross section through the centers of the bases of a cylinder with height of 27 inches and a circumference of about 47.1 inches. Use 3.14 for π.
Answers
Answer:
405 in^2
Step-by-step explanation:
Given data
Height= 27in
Circumference= 47.1 in
let us find the radius and the diameter of the base of the cylinder
from
C=2πr
47.1= 2*3.142*r
47.1= 6.284r
r= 47.1/6.284
r= 7.5 in
Diameter= 2r
D= 7.5*2
D= 15in
Hence the area of the cross-section
=H*D
=27*15
=405 in^2

If the length of the longest side of the rectangle is 20cm find the shaded area to the nearest hundredth
Answers
Answer:
Step-by-step explanation:
diameter of each circle = 20/2 = 10 cm
rectangle is 20 cm by 10 cm
area of rectangle = 20×10 = 200 cm²
radius of each circle = 10/2 = 5 cm
area of each circle = πr² = 25π cm²
shaded area = 200 - 2(25π) = 200 - 50π =42.92 cm²

A teacher purchased 20 calculators and 10 measuring tapes for her class and paid $495. Later, she realized that she didn't order enough supplies. She placed another order of 8 of the same calculators and 1 more of the same measure tape and paid $178.50.The system represents the situation
`20c+10m=495`
`8c+1m=178.50`
Find the cost of one calculator and the cost of one measure tape using one of our methods of solving systems.
Answers
Answer:
Equations are
20c + 10m = 495..............(1)
8c + 1m = 178.5.................(2)
Now , equation (2) * 10 = 80c + 10m = 1785...........(3)
So, Eq. (3) - Eq(1) =
80c + 10m - 20c - 10m = 1785 - 495
60c = 1290
c= 21.5
********************************************************
Now place the value of c in Eq (2)
So , m =6.5
